Where 32 once stood, only four remain. Our competition to name the Greatest Metal Guitarist is starting to wind down, and we've got four of metal's most respected guitarists all gunning for the title.

After a close call with Avenged Sevenfold's Synyster Gates, Slayer's Jeff Hanneman advances to the Semifinals to face Tool's Adam Jones. We've also got immortal Pantera shredder 'Dimebag' Darrell Abbott fresh off his win against Zakk Wylde against Dream Theater master John Petrucci.

Don't worry if you don't see names such as Dave Mustaine, Mikael Akerfeldt or Chuck Schuldiner in these polls, we'll get to them in our upcoming Greatest Metal Frontman competition. We're in the home stretch! Click below to start voting for the Greatest Metal Guitarist.
